Genetics of natural selection: estimating viabilities
We'll start today's lecture (assuming that we don't have another snowstorm that cancels class) by taking questions about the practice exercise I posted last Thursday. Please come prepared with questions. We'll take as much time as we need to make sure all of them are answered.
When we finish with that, we'll take a look at how you can estimate viabilities from data, including a worked example from Drosophila pseudoobscura.
If time permits, we'll spend a few minutes discussing selection when there are multiple alleles or when selection involves fertility rather than viability. If there isn't time to cover those topics in class, I encourage you to take a look at the notes (http://darwin.eeb.uconn.edu/eeb348-notes/selection-multiallele.pdf). Project #3 won't require that you understand any of what's in there, but there are some important ways in which the results of natural selection are more complicated than you might have imagined, and it would be good for you to know that they exist.
